Description
Technical field
The present invention relates to F27 dead burned magnesia roasting kiln field.
Background technology
Magnesite belongs to country's grand strategy resource.China's magnesite reserves account for the 24% of world saving, occupy the world first
Position.Although China is magnesite resource and magnesian big producing country, but owing to blindness for many years is exploited, high-grade magnesite
Stone is the deficientest, and dead burned magnesia produces and remains in the original extensive mode of production, and manufacturing enterprise is simply equipped, and lacks technology
Standard, thermal regulation and rule of operation, the most by rule of thumb manual operation, labor intensity is big, and environmental pollution is serious, and product quality is not
Stable, added value of product is low, and resource can not get comprehensive utilization.The problem basic reason that China's magnesite industry exists is technology and dress
Standby backwardness, has become as the technical bottleneck of restriction China dead burned magnesia development.
China's dead burned magnesia produces equipment and lags far behind developed country, also lags far behind domestic aluminium oxide, cement
Deng other inorganic goods industries.China's dead burned magnesia production technology is original, continues to use traditional shaft furnace always and produces.This shaft furnace
Body of heater is little, and maximum height is less than 18m, yields poorly, and annual production is less than 10,000 tons；Open production, energy consumption is big, pollutes very
Seriously；Barrel shaped structure, viscous stove knot stone roller is serious；Not having distribution device, material directly slips into body of heater from hopper, and cloth is uneven, ore deposit
Stone separates with coal cinder, affects product quality；Artificial discharging, labor intensity is very big, and working environment is the arduousest；Automaticity
Low, produce original, seriously polluted.
Summary of the invention
Solved by the invention technical problem is that cloth of the prior art is uneven, Ore separates with coal cinder in order to overcome
Etc. weak point, and provide a kind of dead burned magnesia roasting kiln revolution multi-point distributing device.
The technical solution used in the present invention is a kind of dead burned magnesia roasting kiln revolution multi-point distributing device, including kiln wall
And kiln crown, kiln crown is provided with hopper, is provided with sub-material taper hole, is provided with at least two cloth below sub-material taper hole below described hopper
Arm, one end of distributing arm is articulated with gyroaxis, and distributing arm is also associated with distributing arm actuator, and distributing arm actuator pulls cloth
Arm rotates upwardly and downwardly the lifting angle of regulation distributing arm vertical direction, and power set are driven back to rotating shaft revolution, and gyroaxis drives cloth
Arm horizontal direction rotates.
Each bar distributing arm cause different in size.
Distributing arm actuator includes undercarriage coaxial mounted with gyroaxis, and undercarriage connects has drag-line, under drag-line
End is connected to distributing arm.
Described undercarriage is driven by motor and moves up and down.
The invention has the beneficial effects as follows, change and reappear the shortcoming having burned magnesium oxide roasting shaft kiln cloth uneven, define
Dead burned magnesia roasting kiln revolution multi-point distributing device, material is assigned to a plurality of distributing arm through sub-material taper hole and carries out cloth, respectively
Bar distributing arm is different in size, and each equal liftable of distributing arm tail end adjusts cloth radius, and speed of gyration is adjustable, many revolution of arms multiple spot cloth
Material, it is achieved that material block is not piled up, Ore and coal cinder does not separates, charge level is smooth without dead angle, effect stability.
Accompanying drawing explanation
Fig. 1 is that dead burned magnesia roasting kiln turns round multi-point distributing device schematic diagram.
Reference: 1-hopper, 2-sub-material taper hole, 3-distributing arm, 4 distributing arm actuators, 41-undercarriage, 42-drag-line,
5-gyroaxis, 71-kiln wall, 72-kiln crown, 73-motor and actuating device.
Detailed description of the invention
The invention will be further described below in conjunction with the accompanying drawings.
Kiln is the critical equipment of dead burned magnesia, and cloth is one of key technology of kiln.As it is shown in figure 1, the present invention
Dead burned magnesia roasting kiln revolution multi-point distributing device, including kiln wall 71 and kiln crown 72, kiln crown 71 is provided with hopper, described
It is provided with sub-material taper hole 2 below hopper, below sub-material taper hole 2, is provided with at least two distributing arm 3, the Ore in hopper and fuel mixing
Material is assigned to each distributing arm by sub-material taper hole, and one end of distributing arm 3 is articulated with gyroaxis 5, its jointed shaft in horizontal direction,
Distributing arm can be realized in perpendicular relative to the angle of gyroaxis 5.Motor is driven back to rotating shaft 5 and turns round, and gyroaxis 5 drives distributing arm
3 horizontal directions rotate.Material is uniformly distributed in kiln by material landing from distributing arm；It is also associated with cloth on distributing arm 3
Arm actuator 4, distributing arm actuator 4 pulls distributing arm 3 to rotate upwardly and downwardly the lifting angle of regulation distributing arm 3 vertical direction, cloth
Arm 3 lifting angle is different, then the radius of gyration of distributing arm 3 tail end is the most different.The most each bar distributing arm 3 is different in size, each cloth
The equal liftable of arm 3 tail end adjusts cloth radius, and speed of gyration is adjustable, many revolution of arms multi-point distribution, it is achieved that material block is not piled up, ore deposit
Stone and coal cinder do not separate, charge level is smooth without dead angle, effect stability.
The lifting angle controlling distributing arm 3 for convenience, distributing arm actuator 4 includes coaxial mounted with gyroaxis 5
Undercarriage 41, undercarriage 41 connects and has drag-line 42, the lower end of drag-line 42 to be connected to distributing arm 3.So driven cloth by motor
Arm actuator 4 rises and falls, it is possible to be uniformly controlled the radius of gyration of each distributing arm 3, and control mode is the most effective.Those skilled in the art
Other lifting or pushing tow mode can also be used as required to realize the control of lifting angle of distributing arm 3, broadly fall into the present invention
The replacement of this technical characteristic of technical scheme.
The dead burned magnesia roasting kiln revolution multi-point distributing device of the present invention, the material of hopper is assigned to through sub-material taper hole
A plurality of distributing arm carries out cloth, and each bar distributing arm is different in size, and the longest distributing arm length can reach more than 2.5m, the shortest cloth
Arm only 10～900mm, the equal liftable of each distributing arm tail end each distributing arm equal liftable of tail end adjusts cloth radius, and speed of gyration can
Adjust, many revolution of arms cloth, it is achieved that expect block not segregation, Ore and coal cinder does not separates, charge level is smooth without dead angle, effect stability.This
Invention has a characteristic that
The most effective, many revolution of arms cloth, expect block not segregation, Ore and coal cinder does not separates, charge level is smooth without dead angle, effect
Stable；
2. simple and flexible, the equal liftable of distributing arm tail end adjusts cloth radius, and speed of gyration is adjustable, simple in construction, runs
Flexibly.
Embodiment is as it is shown in figure 1, Ore and fuel mixture material in hopper 1 are assigned to each cloth by sub-material taper hole 2
Arm 3, distributing arm 3 turns round under the driving of motor, and material is uniformly distributed in kiln by material landing from distributing arm 3, cloth
The angle of arm cloth is regulated by distributing arm actuator 4.The present embodiment kiln height 40m, top diameter 3375mm, produce dead burned magnesia per year
Up to more than 80,000 tons.
